Notes on verification

Figure matches WHO's official statement verbatim and is widely repeated in peer-reviewed literature, but nearly all sources trace back to the same WHO estimate rather than independent measurements. A 2026 umbrella review notes GBD-coded diagnosed cases (~22.3M) are far lower, reflecting a diagnostic gap rather than contradicting the estimate.
